Old Kirk arm-wrestling Young Kirk? It sounds like a what-if of nerdtastic proportions.

Actually, it's how William Shatner began his interview with Chris Pine for his upcoming documentary, The Captains.

"He's shy," Shatner says of the 30-year-old actor who took over the role of James T. Kirk in 2009's Star Trek prequel/reboot. "So the way I started the interview, I put out a table and chairs outside the Paramount gates, and arm-wrestled with him. That was the beginning of my interview with him. I think it broke the ice, that's for sure."

Although Shatner acknowledges the Trek chapter of his career is more or less closed, the documentary, which he directed and expects to air this fall, was the exception. "It's a detailed look at the actors who played the captains on the various iterations of Star Trek."
